lIMPROVEMENT IN NUT-MACHINES.

Specification forming part of Letters Patent No. 193,2B5., dated July 17, 1877 application filed Jim@ 4, 1871.

To all whom it may concern:

Beit known that I, JOHN R. BLAKEsLEE, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in- Machines for Making Hot-Pressed Nuts, of which the following is a specication This invention relates 'to certain improvements in the construction of nut-blanks and apparatus therefor.

The invention consists, first, in the combination, with the cutters, the mechanism for operating the same, and a gage at the rear of said cutters, of a tnishing-die and two pressing-dies, and mechanism for operating the samefas more fully hereinafter set forth; second, in the combination, with the final cutters and the gage, of the series of angular cutters anda hammer located at the rear of each final cutter, for the purpose of squaring the sides of the blank before it is fed to the finishingdie; th-ird, in the combination, with the cutters for cutting the nut-blanks, of a clamp and mechanism for operating the same, to prevent the blanks from cooking during the operation of cutting the nuts, fourth, in the combination, with the cutters and nishing-die, of a gage for holding the end of the blank, supporting it against the action of the final cutters, and retaining the nut when separated in position to enter the iinishingdie, as more fully hereinafter set forth; fifth, in the combination, with the cutters and their operatin g mechanism, and the gage at the rear of said cutters, of the clamps for grasping the blank, and the finishing and pressing dies, and their operating mechanism, the -whole adapted to operate together, as more fully hereinafter set forth.

In the drawings, Figure 1 represents a side elevation broken away, showing section; Fig. 2, a front view; Fig. 3, an enlarged view of die and plungers in act of compressing a nut;

Fig. 4, a plan view. Fig. 5 is an enlarged plan view of cutters in act of cutting off a nut. Fig. 6-is a plan view of cutters opened ready to commence a new nut; Fig. 7, detached views of cutter and partition; Fig. 8, detached views of. the nut.

The letter A represents the bed or frame of the apparatus, constructed of metal or other suit-able material possessing requisite strength. B is a vertical standard upon the upper face of said frame, and C is a hanger below the bed or table for supporting the plungers and the levers by which they are put in motion.

The letter U1 represents the drivin g-shaft of themachine, journaled in boxes D D at the rear of the frame or bed, having a drivingwheel mounted upony one end, by means of which motion is imparted to the various working parts through the medium of suitable cams mounted on the driving-shaft.

The letters E E represent two reciprocating slides adapted to move to and from each other in transverse ways F Fin the upper face of the front of the frame or bed A, said slides being actuated by means of the inclined portions oi` the reciprocating bars G G, which set into and'work in inclined recesses H H in the slides, the said bars being secured in longitudinal ways in the upper face of the table A, inl which they have a reciprocating motion imparted through the medium of the rocking levers l I, pivoted' to the journal-boxes of the driving-shaft, and operated by means of the cams J J, mounted on said rock-shaft.

The inner ends ot' the slides E E are pro-v vided with rectangular recesses e e, for the reception of the cutters e' e e', by means of which the blanks are out. The cutting-ends of said cutters are angular in shape, and two or more of these cutters are employed in each cutter-slide. Three of thesel cutters are representcd, in the present instance, in each cutter-slide. Said cutters are arranged at equal distances apart, being properly spaced to separate the blank at successive progressive cuts each time the cutters approach each other, severing one nut entirely, and making two partial cuts of unequal depths from opposite sides toward the center of the bar at the same time.

The cutters are `preferably separated by means of a series of blanks or partitions, L L L, which are made of gradually-decreasing length, the last or final ones, at the rear of the final cutters, serving as hammers to square the sides of the nut, which become rounded' by the action of the cutters previously to the nut being fed into the finishing-die.

The letter N3 represents a gage located at the rear of the cutters, the object of which is to hold the nut up closely to the action of the final cutters.

The letter Q represents a vertically-reciprocating plunger, carrying at its lower end a die, R, said slide traveling in ways in thefront of the standard B, and actuated therein by' means of a link, S, secured to its upper end and to the forward end of a lever, T, which is operated by means of the' cams U U on the driving-shaft in one directionin the other by means of a spring or other suitable device. Within said= reciprocating plunger Q is a reciprocating bar, W, which carries a piinch Yat its lower end, and is actuated by means of thelever Y and the cani Z on the driving-shaft of the machine.4 j l The letter A' represents a verticalljreciproeating plunger, moving in ways in the hanger C, and provided with a die,A B', at its np'- per end, and is actuated by a lever, O2, which is, in turn, operated by means of a reciprocating bar put in motion by the cam D' on the driving-shaft of the machine. I The letter E' represents the feed-opening of the machine, within which is located a spring clamp, F', having jaws G', which are adapted to act in conjunction with similar jaws H' on the under side of the finishing-die I', to clamp' Vand hold the blank bar, and prevent it fron] cooking during the operation of cntting a hexagonal nut-blank. v Y

The clamp is operated to seize the blank at the proper time by means of a lever', d', eX- tending .under the table to the rear of the' machine, and operated by means of a stud, K', on the cam U. I v Theletter I' represents the ni'sh'ingdie, which is adjustably secured in a recess, M',

belOW the standard B and N1, the clearer c'n-' sisting of a reciprocating rod operated by the' lever O' and cam-'groove P' in the drivingwheel of the machine, to throw the finished nut-blank from the finishing-die. The operation of my apparats is as follows: In commencing', the blank bar is cut in any convenient manner, by hand or other:- wise, properly at the end to subject it properly to the action of the cutters. It is then fed into the machine, with its end resting against the gage, and the machine is put in' operation. l v i The cutters coming together sever the end of the blank,fo"rniing the two' final sides: of the nut, which is separated, and the two in-V itial sides of the succeeding nut on the end of the bar at the same time. This severed blank is' then, by the action of the lower plunger, carried up' into' the finishing-die.

The upperplun ger then advances, and,'ractin g with the lower'plunger, pressesI the nut in the nishingdie, while the punch within the upy per' plunger forms the hole in the nut.

At the next succeeding operation, the nut previously made is forced out of the finishingdie, and is thrown on by the clearer. While thecutters are advancing on the blank bar and cutting into the same, the clamp will be pressed up against it, holding the bar, and preventing any cooking from the action of the cutters in the formation of a hexagonal nut, or the`forcing of the bar backward, and they beveling of the end of the same; in case a square nut is being cut. f

The nut-bar being cut from each side toward the center, the fibers of the finished nut will, by the action o"f the angular cutters, be forced or upset around the sides of the nut in the direction of the length of the bar, w'hereby it will be materially strengthened, and au tendency of the nut to burst at rig-h1; angles will be prevel'lted.

What l claim, and desire to secure' by Letters Patent, is-' I 1. The combination, with the cutters, the' mechanism for operating the same,rand the gage at the rear of said cutters', of the finish ing-die and the compressing-dies and mechanism for operating the same, substantially as set forth..

2'. In combination with the final angular cutters andthe gage, the hammers located at the rear of said cutters, for the purpose of squaring' the sides of the nut-,blank before it enters the finishing-die, substantially as 'set forth. .l

3. In combination `with the cutters for cutting the nutblanks',th'e' clamp for grasping' the blank, and the bent lever and cam for actu: ating thel same, for preventing the bar from cocking during the operation of cutting and severing the nut, Isubstantially as described.

4. Inl combination with the' cutters and inf ishing'die, the gage for holding the end of the blank, supportn'git against the action of the final cutters, and retaining the nut, when separated, in position to enter' the linishingdie, substantially as set forth.

5. The combination,-With the cutters, their operating mechanism, and the gage at the rear of said cutters, of the clamps for grasping the blanks, finishing-die, and the compressing-dies and their operating mechanism, all constructed to operate together substantially as set forth. Y. e

In testimony that I claim the foregoing I have hereunto set my hand in the presence of j the subscribing witnesses.-
